Metrohm Inline Matrix Elimination allows you to separate ionic analytes from the uncharged matrix without the use of sample preparation cartridges (SPE).

Ion analysis in organic solvents is one of the applications.

For trace analysis down to the ng/L range – Metrohm Inline Preconcentration

Metrohm Inline Preconcentration uses a preconcentration column instead of a sample loop. A defined volume of sample is passed over the preconcentration column, the relevant ions are retained, and the accumulated ions are eluted onto the separation column.

Metrohm Inline Preconcentration is ideally suited for trace analysis down to the ng/L concentration range.

Calibration for ultra-trace analysis – Metrohm Inline Calibration

Metrohm Inline Calibration allows you to calibrate any standard concentration in the ng/L range by using a single standard solution at the µg/L level.

This enables accurate and reliable measurements down to the single-digit ng/L range.

Getting the pH right – Metrohm Inline Neutralization

Metrohm Inline Neutralization adjusts the pH of samples in order to prevent interferences with the analysis of anions.

When combined with Inline Preconcentration, Inline Neutralization makes trace anion analysis possible. Adjusting the pH right also prolongs the lifetime of the column.

Preparing gaseous samples – Monitor for Aerosols and Gases (MARGA)

In addition to the aerosol fraction of ambient air, MARGA also collects the ionic load of the gas fraction and brings it into the aqueous phase for subsequent analysis by dual channel ion chromatography.

MARGA is designed for continuous, unattended operation in the field. Read more about MARGA here.

Preparing combustible samples – Combustion Ion Chromatography (CIC)

In CIC, samples are digested by pyrolysis in an oven unit. The resulting gaseous compounds are passed into an absorption solution, which is transferred to a Metrohm ion chromatograph for subsequent injection and analysis.

CIC is the preferred method to determine various halogens and sulfur in matrices ranging from solids to viscous, liquid, and gaseous samples.
